He further turned his attention to matters of local improvement. He got pavements laid; and even brought about the sweeping of the streets twice in each week. Lighting the streets came almost simultaneously; and in connection with this he showed his wonted ingenuity. Globes open only at the top had heretofore been used, and by reason of the lack of draft, they became obscured by smoke early in the evening. Franklin made them of four flat panes, with a smoke-funnel, and crevices to admit the air beneath. The Londoners had long had the method before their eyes, every evening, at Vauxhall; but had never got at the notion of transferring it to the open streets.
For a long while Franklin was employed by the postmaster-general of the colonies as "his comptroller in regulating several offices and bringing the officers to account." In 1753 the incumbent died, and Franklin and Mr. William Hunter, jointly, were appointed his successors. They set to work to reform the entire postal service of the country. The first cost to themselves was considerable, the office falling more than £900 in debt to them during the first four years. But there-afterward the benefit of their measures was felt, and an office which had never before paid anything to that of Great Britain came, under their administration, "to yield three times as much clear revenue to the crown as the post-office of Ireland." Franklin narrates that in time he was displaced "by a freak of the ministers," and in happy phrase adds, "Since that imprudent transaction, they have received from it--not one farthing!" In this connection it may be worth while to quote Franklin's reply to a request to give a position to his nephew, a young man whom he liked well, and otherwise aided. "If a vacancy should happen, it is very probable he may be thought of to supply it; but it is a rule with me not to remove any officer that behaves well, keeps regular accounts, and pays duly; and I think the rule is founded on reason and justice."
At this point in his autobiography he records, with just pride, that he received the degree of Master of Arts, first from Yale College and afterward from Harvard. "Thus, without studying in any college, I came to partake of their honors. They were conferred in consideration of my improvements and discoveries in the electric branch of natural philosophy."
